I just got into usenet and some of the files downloaded are ISOs. I’m trying to figure out the best way to convert them to mp4s so that I can play them through plex. I’m running on a headless arch server (Manjaro), and I’d prefer to keep the conversion there if possible.

Anyone have experience with this?

I was so confused because all my isos are of operating systems

[–] Double_A@discuss.tchncs.de 9 points 1 year ago (2 children)

I know you're joking, but actually most ISOs I have are actually operating systems or games. I've never seen a normal movie release as an ISO, except maybe 1:1 copies of retail disks.

[–] Cqrd@lemmy.dbzer0.com 2 points 1 year ago (1 children)

Radarr seems to love finding blu-ray quality movies as ISOs

[–] AphoticDev@lemmy.dbzer0.com 4 points 1 year ago

Add ISO to the extension blacklist in SAB so that the download fails and Radarr tries a different one.

[–] Dohnakun@lemmy.fmhy.ml 1 points 1 year ago

If they are backups, rather name them .img.

Handbrake reads and converts DVD movie and video ISOs. If they are encrypted, MakMKV and DVDDecrypter can be used to get them ready for Handbrake.

[–] Cqrd@lemmy.dbzer0.com 2 points 1 year ago (1 children)

I've tried HandBrakeCLI and for some reason it detects all tracks as 5 seconds and outputs a 2.4mb file from a 29gb ISO. Does this mean they're encrypted?

[–] dishpanman@lemmy.ca 2 points 1 year ago (1 children)

If it's a 29GB ISO it's definitely not a DVD but likely a BluRay. It may be encrypted/corrupted/not a video. Try MakeMKV next to see if it can decrypt and recognize the chapters.

[–] Cqrd@lemmy.dbzer0.com 3 points 1 year ago (2 children)

Does MakeMKV have a command line tool for Linux? I’m trying to do this all through ssh

[–] dishpanman@lemmy.ca 3 points 1 year ago (2 children)

I believe they do. Their Linux installer link is buried in the forums: https://forum.makemkv.com/forum/viewtopic.php?f=3&t=224

They have batch ISO convert CLI for Windows: https://forum.makemkv.com/forum/viewtopic.php?f=10&t=15426

You may need to network share your headless seedbox or whatever you have the ISO on to do this off a linux or Windows machine.

[–] Cqrd@lemmy.dbzer0.com 2 points 1 year ago (1 children)

Turns out makemkv is on AUR so I was able to yay -S makemkv and one of the options was the CLI! After this I was able to run makemkvcon mkv iso:<file> all <dir> and it seems to be working! Thank you so much for your help

[–] dishpanman@lemmy.ca 1 points 1 year ago* (last edited 1 year ago) (1 children)

I'm glad I could help! Can you post the CLI command syntax that worked for you to run makemkv to decrypt your ISO? It will help others are trying to figure this out in the future. Or was it just the single command you posted?

[–] Cqrd@lemmy.dbzer0.com 1 points 1 year ago* (last edited 1 year ago) (1 children)

Oh, I did in my comment. It was just:

makemkvcon mkv iso:my_file_name.iso all outputDirectory

Note: outputDirectory must exist, it could even just be ./

makemkv will then scan the iso for its chapters, filter out the small ones, convert the large ones to mkv files and output them in your directory you provided. Then I just looked for the biggest one and deleted the smaller ones, the big one ended up being almost the same size as the ISO and was indeed the movie output I was looking for.

[–] dishpanman@lemmy.ca 1 points 1 year ago (1 children)

Thanks for following up! I'm surprised it just dumped out one mkv file without you having to command a specific chapter to decrypt. It's good to know that you can probably set up a batch file to decrypt everything in a whole directory!

[–] Cqrd@lemmy.dbzer0.com 2 points 1 year ago

Well the all parameter had it convert all the ones big enough, I ended up with 3 then just paired it down to the one I cared about.

[–] BitterSweet@discuss.tchncs.de 2 points 1 year ago

Thank you kind sailor!

[–] dishpanman@lemmy.ca 2 points 1 year ago

Here are makemkvcon syntax parameters for you to try: https://bluray.beandog.org/makemkv/man/makemkvcon.html

I think this is the best response for OP!

Mount that shit

[–] mp3@lemmy.ca 8 points 1 year ago (1 children)

Handbrake is able to "mount" ISOs, should be pretty straightforward from there.

[–] Cqrd@lemmy.dbzer0.com 1 points 1 year ago

I've tried HandBrakeCLI and for some reason it detects all tracks as 5 seconds and outputs a 2.4mb file from a 29gb ISO

[–] H_Interlinked@kbin.social 5 points 1 year ago

I've always used Free ver. of PowerISO to "mount" the disc image to a virtual drive like others mentioned. Anyone who's emulated PlayStation 1/2 games would be very familiar with this format. Otherwise any old software released on CD format you'll probably find as an ISO.

[–] CorrodedCranium@lemmy.fmhy.ml 5 points 1 year ago (1 children)

Can you mount them? If so what does that look like?

[–] div@kbin.social 1 points 1 year ago (1 children)

If you are in windows, right click on the iso and the option to mount the image should come up. Once mounted it should look like a DVD or CD was inserted and should behave as such.

[–] Bombastic@lemmy.dbzer0.com 3 points 1 year ago (1 children)
[–] CorrodedCranium@lemmy.fmhy.ml 1 points 1 year ago

Should be similar on most Linux distros.

[–] TwilightKiddy@programming.dev 4 points 1 year ago* (last edited 1 year ago) (1 children)

If there is no encryption involved, you should be able to unpack them with 7zip without any mounting and then convert with ffmpeg to a format of your liking. IIRC, DVDs usually consist of a bunch of VOB files. You can just cat them all together and then send directly to ffmpeg.

[–] Dohnakun@lemmy.fmhy.ml 1 points 1 year ago (1 children)

Cating them together does only work in some cases though.

[–] TwilightKiddy@programming.dev 1 points 1 year ago (1 children)
[–] Dohnakun@lemmy.fmhy.ml 2 points 1 year ago

No, sorry. Only thing i remember the Stackoverflow post warning about some conditions and it didn't work for me.

[–] rouxdoo@kbin.social 4 points 1 year ago

I would imagine if they are ISOs a DVD converter would probably work.

[–] flying_monkies@kbin.social 2 points 1 year ago

mkdir /mnt/iso
sudo mount -o loop /path_to_iso/filename.iso /mnt/iso

[–] S0berage@mstdn.ca 2 points 1 year ago

@Cqrd i use wincdemu to mount and 7zip to unzip contents without mounting on windows boxes, same for Linux but wincdemu is cdemu, fuseiso, acetoneiso or brasero

I’d like to recommend using DVDFab for converting your ISO files to MP4 format. It's available on Linux, including your Manjaro setup. If you encounter any issues with encrypted DVDs, you might also need to consider tools like MakeMKV for decryption. Just keep in mind that MakeMKV is typically used to extract the video without compression, so you can then use DVDFab HD Decrypter afterward to convert to MP4 if needed.

[–] dan@social.fossware.space 2 points 1 year ago

Use ffmpeg to convert them

[–] Dohnakun@lemmy.fmhy.ml 1 points 1 year ago

Mount them and move stuff over.

[–] nothacking@discuss.tchncs.de 1 points 1 year ago (1 children)

Handbrake can convert DVD images into other formats if that's what you have. (7ish gigs each)

[–] Cqrd@lemmy.dbzer0.com 1 points 1 year ago (1 children)

I've tried HandBrake and for some reason it detects all tracks as 5 seconds and outputs a 2.4mb file from a 29gb ISO

Try messing around with feature selection, or try with "--main-feature".
